### 在Etherscan上查询事件

我们尝试用`_transfer()`函数在`Rinkeby`测试网络上转账100代币，可以在`Etherscan`上查询到相应的`tx`：[网址](https://rinkeby.etherscan.io/tx/0x8cf87215b23055896d93004112bbd8ab754f081b4491cb48c37592ca8f8a36c7)。

点击`Logs`按钮，就能看到事件明细：

`Topics`里面有三个元素，`[0]`是这个事件的哈希，`[1]`和`[2]`是我们定义的两个`indexed`变量的信息，即转账的转出地址和接收地址。`Data`里面是剩下的不带`indexed`的变量，也就是转账数量。
